A global leader,not a gamble.
The machine control behind Green Grade is built by one of the world's largest precision positioning companies — designed, manufactured and programmed under one roof, and proven on worksites in 140+ countries.
Big enough to trust. Built to compete.
Listed, audited, accountable
The company
CHCNAV — Shanghai Huace Navigation Technology — was founded in 2003 and has been a public company on the Shenzhen Stock Exchange since 2017 (ticker 300627). Audited financials, published filings and thousands of shareholders. This is not a pop-up importer: it's an established technology company you can look up, with the balance sheet to stand behind its warranty.
From chip to cab
In-house everything
More than 1,000 R&D engineers across research centres in Shanghai and Wuhan design their own GNSS boards, smart antennas, IMUs, displays and the proprietary iStar RTK engine. The hardware isn't bought in and badged — it's built from the component up, the same vertical integration the legacy brands built their names on.
One system, not a patchwork
The software stack
MCSite cloud, iSite over-the-air updates, the office tools and the file formats your jobs already speak — LandXML, DWG, DXF. Because the software is written alongside the hardware it runs on, receivers, displays and the cloud move as one system instead of a bundle of somebody else's parts.

A world leader, by the numbers
Global scale
CHCNAV sells into 140+ countries with subsidiaries in Europe and North America, and is the world's largest supplier of GNSS smart antennas — 100,000+ shipped every year. Four product lines — geospatial, machine control, precision agriculture and OEM positioning for autonomy — compete head-to-head with the systems you already know, at global scale.
